9.2 Comprehensive Configuration Management
For adapters that include CCM firmware (legacy boot only), preboot configuration can be configured using the
Comprehensive Configuration Management (CCM) menu option. During the system BIOS POST, the Broadcom banner
message is displayed with an option to change the parameters through the Control-S menu. When Control-S is pressed, a
device list is populated with all the Broadcom network adapters found in the system. Select the desired NIC for configuration.
NOTE:
Some adapters may not have CCM firmware in the NVRAM image and must use the HII menu to configure legacy
parameters.
9.2.1 Device Hardware Configuration
Parameters that can be configured using this section are the same as the HII menu Device level configuration.
9.2.2 MBA Configuration Menu
Parameters that can be configured using this section are the same as the HII menu NIC configuration.
9.2.3 iSCSI Boot Main Menu
Parameters that can be configured using this section are the same as the HII menu iSCSI configuration.
9.3 Auto-Negotiation Configuration
NOTE:
In NPAR (NIC partitioning) devices where one port is shared by multiple PCI functions, the port speed is
preconfigured and cannot be changed by the driver.
The Broadcom NetXtreme-E controller supports the following auto-negotiation features:
Link speed auto-negotiation
Pause/Flow Control auto-negotiation
NOTE:
Regarding link speed AN, when using SFP+, SFP28 connectors, use DAC or Multimode Optical transceivers
capable of supporting AN. Ensure that the link partner port has been set to the matching auto-negotiation protocol.
For example, if the local Broadcom port is set to IEEE 802.3by AN protocol, the link partner must support AN and
must be set to IEEE 802.3by AN protocol.
NOTE:
For dual ports NetXtreme-E network controllers, 10 Gb/s and 25 Gb/s are not a supported combination of link
speed.
